FILTER.

Application filed August 13,

Our invention relates to filters, our aim being to provide a simple and effective device that can be manufactured at relatively low cost, and can be easily and quickly opened, cleaned, and returned to service. The embodiment of our invention here shown and described is well suited for use in fuel oil lines and the like; I

The accompanying drawings illustrate the preferred form of the invention, though it is to he understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the'claims will voccur to persons skilled vin the art.

The 'inlet and outlet 6 are shown at the upper part of the filterca-sing, in alignment with one another at opposite sides thereof, and the filter chamber 10 liesbelow them. The inlet and outlet 5, 6 are separated from one another by'an internal dividing strifeture or partition, which. also separates one of them (the inlet 5) from the filter chamber 10. s here shown, the partition comprises a vertical wall 11 opposite theout'let'6, -and a horizontal wall 12 extending fronithe lower end of thewall 11 to the other/side of the casing, below the inlet 5, jvith an opening 13 therein. At the-bottom ofthe chamber 10, there is a clean-out opening- 14 in the casing wall, opposite tlie'opening 1 3' and in direct axial alinement there 't-h, but

somewhat larger than the opening 13. opening 14 is provided with a removable closure in the form of a screw plug 15. The

plug 15 is shown ashaving a double wing handle 16 for screwing it home, and unscrewing it, A (lead) gasket 17 Set a the lower ring 24.

The filter 20 is of hollow cylindrical form, and extends substantially from the bottom of the 'chamber 10 to the horizontal partition wall 12, around the opening'l3 in the latter.

It will be seen that the device-is simple, rugged,.easy and convenient to install and keep in order, and very, economical to manufacture, since the only rtions or surfaces requiring any careful finish are the'tap'ped openings in the filter and the suriaees involved inseatmg the structure 21 at p 13 and in the mount ng and seating of the Also, the fi ter gauze at 20 can ily removed and replaced when he very ea otherwise deteriorated.
